Its happening because people’s brains are ‘adapting’ to the short form, brainrot mode of modern social media.
This is what I feared way back when Twitter first gained popularity. I couldn't get into it, because the short character limit made it impossible to explain pretty much anything.
Anyway, I'm with you on this. If you've got something important or novel to share, it's probably going to take some explanation to convey it. Short-form social media leads to shallow conversations. I like depth, I like exploring others' perspectives, and it takes more than 160 characters (or whatever the limits are now) to really reach some subjects.
I say this as someone with unmedicated ADHD - modern people's attention spans are depressing. I still love watching documentaries that are 2+ hours long, even when YouTube tries to push for 30-second clips of garbage. Thank goodness for Lemmy and Mastodon, offering us the chance to really dive deep into conversations that most social media want to clip short.
